Extreme models are massive binoculars that use uncompromising solutions. When designing them, the best optical properties supported by solid mechanics were a priority. That's why the porro prism was used and low-dispersion elements as well as massive prisms made of high-quality BaK-4 glass were used.

Thanks to ED lenses, the chromatic aberration is significantly reduced in the image, and thanks to the powerful prisms, you do not have to worry about vignetting and darkening the image at the edge of the field of view. In addition, the Extreme binoculars are equipped with modern antireflection coatings (FMC), which cover all optical elements. This guarantees over 90% transmission of light throughout the system, and thus, a bright and extremely realistic picture with a natural color reaches our eyes. The image is free from such defects as astigmatism or coma, and thanks to the correct correction of distortion the image is perfectly flat.

All these features add up to one of the most important - Delta Optical Extreme binoculars give an extremely bright, sharp and contrasting image in the whole field of view!

Model 10x50 is a construction with parameters tested by users and considered universal. The magnification is large enough to see small details, but also small enough to avoid image shake and maintain its brightness. These binoculars can be used for hunting purposes.

As a very durable equipment it will also be useful in professional applications, such as property protection and as equipment for various types of services. Nature observers can also appreciate the quality of this equipment - the image obtained will be bright, contrasting, with great colors, and because of the glass species used - very detailed. Extreme 10x50 has a tripod socket, which should be used with this type of observation.

The bodies of all Extreme models are made of durable metal and covered with a special rubber veneer, which in addition to good grip, provides effective cushioning when the binoculars fall or hit it. Mechanics in these devices can work in a wide temperature range from -40 to 70 ° C.

An important feature of Extreme is also full water resistance and protection against fogging from the inside, in the form of pure nitrogen, which the binoculars are filled with. Thanks to the large size of Extreme binoculars, you can easily handle them with gloves in winter conditions.

All Delta Optical Extreme models have an individual focusing system.

Comfortable eyecups adhere well to the eyes, cutting off the light coming from the outside. In combination with a large distance from the eyepiece of the eyepiece, this ensures comfortable observation.
